Remote-control movable bump for temporary traffic-control purpose

ABSTRACT

A remote-control movable bump for temporary traffic-control purpose includes a movable and combinable main body of trapezoid shape so as to define a slope on front and back side, a plurality of vertical slots formed spaced apart in one of the slopes, a shaft rotatably disposed in a center of the main body having a hexagon recess in one end and a protrudent rectangular recess on the other end engageable with a rectangular axis of an alternately rotated motor, a plurality of tipped blades integrated with the shaft and engaged within the vertical slots respectively and a remote sensor to actuate the motor which operates the shaft to rotate for lifting the tipped blade up for about 45°.

BACKGROUND OF THE INVENTION

The present invention relates to abatises or other road obstacles and more particularly to a remote-control movable bump for temporary traffic-control purpose which is combinable to fit the width of the road and readily to block or to open the traffic of the road.

In modern society, the criminal act such as the robberies, the murders and/or the kidnaps trends to grow more and more. In order to defend these outlaw cases, the policemen are always tired from running around and sometimes use the abatis to block a road to prevent the rioters from escaping and try to arrest them. However, these abatises are made of barbed-wire or fences that could not stop the rioters driving a car from dashing over even causes the casualties of the policemen.

Many parking areas of government buildings, supermarkets and parks dispose a stationary tipped bump at their entrance and exit. The tips of the bumps are movable and toward opposite directions. When a car is passing through, the tips will be pressed down and automatically lifted up after the car is passed through, so that the car can only drive on one direction and cannot drive backward. This arrangement aims to save manpower and effectively prevents the parking cars escaped from the parking area. Because this type of bump is stationary and its tips are uncontrollable that lessens its value of utilization.

SUMMARY OF THE PRESENT INVENTION

The present invention has a main object to provide a remote-control movable bump for temporary traffic-control purpose in which the up and down movement of the tips are remote controlled and are operated at a critical situation. Further, it is of good mobility and can control the cars from opposite directions.

Another object of the present invention is to provide a remote-control movable bump for temporary traffic-control purpose which is combinable to cope with the width of the road.

Accordingly, the remote-control movable bump of the present invention comprises:

a movable main body of predetermined length and a trapezoid section so as to form a slope in front and back sides, a plurality of vertical slots formed spaced apart in one of the slopes,

a shaft rotatably disposed in the center of the main body having a hexagon recess in a left end, a protrudent rectangular recess on a right end engageable with hexagon recess and a plurality of tipped blades spacedly integrated with the shaft engageable with the vertical slots respectively,

a motor having alternate circuit therein and a rectangular axis engageable with protrudent rectangular recess,

The feature is that a policement uses a remote sensor to actuate the motor to rotate the shaft clockwise or counterclockwise so as to make the tipped blades lifting upward of retreating downward to hide in the vertical slots. When the tipped blades are lifted up, the tires of the car from either directions will be stabbed at and can't move continuously.

The present invention will become more fully understood by reference to the following detailed description thereof when read in conjunction with the attached drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to the drawings and initiated from FIGS. 1, 2 and 3, the movable bump of the present invention comprises generally a main body 10, a shaft 11, a plurality of tipped blades 12 and a motor 20.

The main body 10 has predetermined length and width and a trapezoid section so as to formed a pair of slopes on front and backside, a plurality of vertical slots 13 formed spaced apart in one of the slopes for respectively engaging within the plurality of the tipped blades 12 which are integrated with the shaft 11 disposing in a center of the main body 10 and beared by a pair of bearings 14 at two ends. The shaft has a hexagon recess 112 in a left end and a protrudent rectangular recess 111 in a right end engageable with the hexagon recess 112. The motor 20 has an alternate circuit and a rectangular axis 21 engaged with the rectangular recess 111 when assembling. The motor is actuated by a remote sensor (not shown) which has different push buttons to control the motor 20 to rotate clockwise or counterclockwise or stopping the rotation. The shaft 11 is rotated in concert with the motor. When the shaft 11 rotates clockwise, the tipped blades 12 are all lifted up until the tips toward upward. When the shaft 11 rotates counterclockwise, the tipped blades 12 are moving down to hide in the vertical slots 13.

In operation (as shown in FIGS. 4 and 5) in a critical moment, the policement be promptly move the movable bump 10 and put it on a junction of a road or the entrance ramp and exit ramp of a freeway and control the motor 20 immediately performing a clockwise rotation so as to lift the tipped blades 12 up to its up-most position (about 45° relative to the ground). So any car tries to dash over the bump 10, its tires should be stabbed through and no longer to drive on so that the rioters in the car have no way to escape but to be caught by the policemen.

Referring to FIG. 6, if the bump 10 is too short to block the road. One of more bumps 10 can be combined together to cope with the width of the road. The manner is that engage the protrudent rectangular recess 111 within the hexagon recess 112 of the next bump 10 and so on till the protrudent rectangular recess 111 of the last bump 10 engaged with rectangular axis of the motor 20, the combination of the bumps 10 is therefore completed.

Except the above discussed horizontal combination, the bump 10 of the present invention is capable of multiple overlapped combination. But needs more than one remote sensors to effectively control the up and downward movement of the tipped blades 12. At any rate, this type of movable bump provides greater mobilization to prevent outlaw activities.

Note that the specification relating to the above embodiment should be construed as an exemplary rather than as a limitative of the present invention, with many variations and modifications being readily attainable by a person of average skill in the art without departing from the spirit or scope thereof as defined by the appended claims and their legal equivalents.
